Many different species of birds make their home in the Forest. From the woodland birds that live amongst the trees, to the many wild fowl on the lake, to the more recent sightings of spectacular birds of prey.

Hatfield Forest is home to a large population of Fallow and Muntjac deer. Fallow deer were introduced into the Forest in the 1100s. They are by nature shy animals and tend to keep to the quieter parts of the Forest.
